so as the title states my nitrates shot through the roof in a day.... Nothing died in the tank and I did a 20 percent water change today and decided to check my nitrates after and they are through the roof. I checked my top off water and that is through the roof and I checked my rodi water and that's through the roof. Could it be my salifert test has gone bad? I left the bottle cap open for a while.
